Ecu flash with supporting mods?! Help!

Hello and thanks in advance for help! Sadly rumblebee is caged currently due to spring acting like a deadbeat father, so with the anticipation building I have decided to why not spend some unnecessary money on parts since the petrol bill is low. With that said I am soon the send the ecu to nels @ 2wdw because from reading other posts he seems to be the godfather of fz's with that said I figure I may spend a few more dollars on other upgrades because it's what we do here! So currently I am trying to compile a list of performance boosters that work well with the bike. Speigler lines and new pads will be added soon then and later down the road a bigger brake improvement may be made, but until then for the motor and flash what would some good combinations to start off with for performance. Once again thanks in advanced everyone!
